External Route Summarisation
----------------------------

This feature summarises originated external LSAs (Type-5 and Type-7). Summary
Route will be originated on-behalf of all matched external LSAs.

.. cfgcmd:: set protocols ospf aggregation timer <seconds>

Configure aggregation delay timer interval.

Summarisation starts only after this delay timer expiry.

.. cfgcmd:: set protocols ospf summary-address x.x.x.x/y [tag (1-4294967295)]

This command enable/disables summarisation for the configured address range.

Tag is the optional parameter. If tag configured Summary route will be
originated with the configured tag.

.. cfgcmd:: set protocols ospf summary-address x.x.x.x/y no-advertise

This command to ensure not advertise the summary lsa for the matched
external LSAs.
